Everything you need to know about sending alerts and notifications with Sakura SMS.
Alert messages sent through Sakura SMS are delivered within 1-3 seconds on average. When you set priority to high, your messages are routed through our dedicated priority queue, which bypasses standard throughput limits and connects directly to MNO fast lanes. We maintain direct SMPP connections to all four Tanzanian operators for minimal latency.
Yes. You can pass an array of recipient numbers in a single API call for broadcast alerts, or use audience segments for targeted notifications. Our platform handles parallel delivery across all MNOs and provides individual delivery receipts for each recipient. There is no separate bulk endpoint -- the same API scales seamlessly.
Priority routing assigns your message to a dedicated high-throughput queue that is separate from standard promotional traffic. Priority messages skip the standard queue entirely and are submitted to the MNO within milliseconds. This is ideal for transaction alerts, security notifications, and emergency broadcasts where every second counts.
Our platform automatically retries failed deliveries up to three times with exponential backoff. If the message still cannot be delivered (for example, if the handset is off), we send a delivery failure webhook to your callback URL with a detailed reason code. You can configure fallback channels such as WhatsApp or voice to ensure critical alerts always reach the recipient.
Yes. Include a send_at parameter with an ISO 8601 timestamp in your API request, and the message will be queued for delivery at that exact time. This is useful for appointment reminders, scheduled maintenance notifications, and recurring alerts. You can also cancel scheduled messages before they are sent.
Every message returns a unique SID that you can use to query its status via our API. We also send real-time delivery receipts to your webhook URL, including timestamps for queued, sent, delivered, and failed states. The dashboard provides aggregate analytics including delivery rates, latency percentiles, and failure breakdowns by MNO.
